Infineon makes smart and sustainable homes based on Matter a reality

Smart home solutions increase consumers’ convenience while reducing energy consumption and lowering consumers’ carbon footprints. However, different device ecosystems, products and protocols have made implementing a truly connected, secured smart home difficult until now. The Connectivity Standards Alliance’s (CSA) newly released Matter 1.0 specification helps alleviate these challenges by offering one unified standard for device makers to follow for many smart home applications including smart locks, lighting, thermostats, security systems, sensors and media devices. Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY), a world leader in IoT and power solutions, has joined CSA and more than 280 companies to pioneer the game-changing Matter standard to make ease-of-use, interoperability, security and sustainability a reality in the smart home.

“Our homes are the center of our daily activities, from work to leisure,” said Thomas Rosteck, Division President Connected Secure Systems at Infineon. “We believe that having one standard solves the fragmentation of the smart home market, which will be the key in opening doors to drive better connectivity, digitalization and decarbonization in this market. The Matter initiative and Infineon’s integrated Matter solutions will allow consumers to customize, connect and control their smart home experience in a simple and secure way, while optimizing energy usage in the most effective manner.”

Matter 1.0 will accelerate adoption of smart home solutions by proving interoperability and backwards-compatibility of devices from different brands and operating systems.

Infineon leaders sit on the CSA board, underscoring the company’s commitment to advancing global standards and helping to shape the future of IoT in the smart home. The world leader in hardware-based security solutions, also leads major security teams covering topics such as encryption, device attestation and integrity as well as security certification of smart home devices.

Smart Home market to grow rapidly

According to market research firm ABI Research, by 2030, more than 1.5 billion Matter certified devices will ship annually (Source: ABI Research, Smart Home Bi-Annual Update, March 2022). In addition, over that period, a vast range of consumer robotics, smart appliances, and other emerging smart home device types are expected to be drawn into smart home system engagement.

Beyond convenience and automation, connected devices and services in the smart home will provide energy-efficient solutions to solve social and environmental challenges.

Within total worldwide electricity consumption, residential buildings make up 29 percent. Space cooling, heating and refrigeration are among the largest power consumers. Here, the interconnection of smart things opens up great potential for reducing energy consumption. For example, smart home networks can learn users’ personal temperature preferences in different situations to adapt them automatically. Sensor-based controls can turn off lights, heating and air conditioning when no one is in the room. And intelligent smart home networks can start washing machines or car charging when renewable energies are available.

With one out of six people in the world being aged 60 years or over by 2030, smart home solutions can also help seniors to stay independently and more comfortably in their own homes.

Six external magnetic mount antennas serve 5G, ISM and LPWA applications

Linx Technologies has introduced six external magnetic-mount antennas serving 5G cellular, ISM (industrial, scientific and medical) and low power wide area (LPWA) applications.

Two models, the ANT-2.4-MMG1-SMA and ANT-2.4-MMG2-SMA are designed for Wi-Fi / WLAN and 2.4 GHz ISM band applications such as Bluetooth and Zigbee. 

Two others, the ANT-5GW-MMG1-SMA and ANT-5GW-MMG2-SMA antennas are designed for 5G New Radio, LTE and cellular IoT (LTE-M, NB-IoT) applications. 

The final pair, the ANT-8/9-MMG1-SMA and ANT-8/9-MMG2-SMA antennas are designed for use in 868 and 915MHz bands for low power wide area (LPWA) applications such as LoRaWAN and Wi-Fi HaLow, as well as ISM and remote control applications.

All six antennas provide ground plane independent dipole antenna options which mount to ferrous metallic surfaces via an integrated magnetic base. The antennas terminate in an SMA plug (male pin) connector on a one, two or three metre length of RG-174/U coaxial cable.

The magnetic mount antennas enable users to expand the reach of their systems by mounting the antenna away from the radio, commented Rick Stuby, Linx Technologies’ vice president of product management. The small size makes them inconspicuous and easy to manage, he added.

The magnetic mount antennas are available now via Linx Technologies’ distributor and manufacturer representative networks.

Linx Technologies strives to minimise the risk, delays, and technical challenges for design engineers to make products wireless and connect them to the IoT. 

Linx manufactures wireless components including antennas, RF connectors and cables, RF modules and remote controls. The company is part of TE Connectivity, a sensor and connectivity provider whose products are proven in the harshest environments, enable advancements in transportation, industrial applications, medical technology, energy, data communications and the home, said the company.

5Mpixel image sensor is sensitive for professional security cameras

The OS05B is a 5Mpixel CMOS image sensor has a 2.0 micron pixel in a 1/2.78 inch optical format that has high sensitivity and dynamic range for professional and high end security cameras, said Omnivision.

The OS05B CMOS image sensor can also be used in industrial and factory surveillance systems, webcams and high-end baby monitors. It is based on the PureCel Plus technology and features Omnivision’s Nyxel near-infrared (NIR) technology for crisp, clear images in low light conditions.

According to Cheney Zhang, senior marketing manager at Omnvision, the OS05B, is available as an upgrade to the OS05A image sensor, introduced five years ago. It is claimed to have the best NIR QE and low-light performance in a 5Mpixel, small package size. “The OS05B is ideal for professional security cameras, for example in industrial and factory applications, where it is important to capture clear video at night while also maintaining low power,” he added.

Signal to noise ratio has been improved by 32 per cent, compared with the OS05A, and NIR QE at 940nm is improved by 24 per cent. The OS05B also has selective conversion gain which increases sensitivity and reduces the readout noise level for optimum SNR under low-light conditions. Low conversion gain also achieves a higher full well capacity in bright conditions. It captures high resolution video at 60 frames per second with two-exposure staggered HDR. The OS05B supports MIPI and LVDS interfaces. 

Samples of the OS05B are available in Q4 2022, and it will be in mass production in Q1 2023.
